Story 
"Lucy in the Sky with Diamonds" is a song by the English rock band the Beatles from their 1967 album Sgt. Pepper's Lonely Hearts Club Band. It was written primarily by John Lennon with assistance from Paul McCartney, and credited to the Lennon–McCartney songwriting partnership. [Wikipedia]
Lucy in the Sky with Diamonds is a song by The Beatles, written by Lennon and led on vocal by John Lennon. Title from son Julian's drawing; not LSD per se, says John. John Lennon drew the title from his three-year-old son Julian's nursery-school painting of a classmate named Lucy. Despite the coincidental LSD acronym, George Martin firmly denied drug inspiration, attributing the song's kaleidoscopic imagery to Lennon's imagination alone. The composition exemplifies the era's psychedelic aesthetic, with its Carroll-inspired lyrical landscape and ethereal sonic textures (Lewisohn 1988, p.100). The song title came from a drawing by John's son Julian and drew imagery from a scene in Alice in Wonderland, following Lennon's pattern of finding song ideas in visual art (Kozinn 1995, p.157).
The session work falls within the band's Sgt. Pepper's (1967) period, recorded 28 Feb 1967 at EMI Studios, Abbey Road. George Martin produced; Geoff Emerick engineered. Lengthy rehearsals on 28 February preceded the rhythm-track recording on 1 March, captured with varispeed at 46½ cycles per second to accelerate the final playback. The Hammond organ—played by Paul and registered like a celeste—created the song's distinctive opening. Paul's bass contribution proved notably unconventional, positioning notes off-standard harmonic placement to expand tonal palette. Multiple overdubs and remixes followed, with Lennon's vocal recorded at 45 cycles (Lewisohn 1988, p.100-101).
Emerick recalls John's exchange with George Martin about a 'funny nose,' and notes that the track became one of his favorites on the album despite the BBC's later banning of the title for its LSD acronym (Emerick 2006, p.454). MacDonald critiques the song's structure, noting that the final 4/4 rock section shatters the lulling atmospheric spell the track carefully establishes, though the glamorous production partially compensates (MacDonald 1994, p.103).
